U.S. sprinter Mike Rodgers, tested positive for a stimulant, was provisionally suspended and retired from the U.S. team for the World of Daegu, which begin Aug. 27, said the U.S. Anti-Doping Agency (USADA) on Friday.

“Mike Rodgers has accepted a provisional suspension on Friday and withdrew voluntarily World-2011 in Daegu (South Korea), where he was enrolled in 100 m and 4×100 m,” said USADA said in a statement.

Rodgers, 26, was replaced by 100 m by Trell Kimmons, who was already part of the pool of sprinters for the US 4x100m relay, then announced the American Federation (USATF) in a statement.

Kimmons took 4th place Championship of the United States, selective for the World. Rodgers took the third and final qualifying spot of the event contested in June in Eugene (Oregon), before a positive control.

Rodgers, the fourth best performer of the season with 100 m 9 sec 85 and champion of the United States in 2009, tested positive for a stimulant (methylhexaneamine) at the meeting in Lignano (Italy) in July.

According to his agent Tony Campbell, who revealed the positive test last week, the product in question was contained in an energy drink.

“Rodgers maintains his innocence and assures that he did not intentionally ingested the banned substance, but decided not to participate in the World out of respect for other athletes, who will not suffer the distraction created by the positive control “said USADA.

The penalties for testing positive for a stimulant range from a warning to several months of suspension.
